ATTACHMENT FOR ROLLING-MILLS.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed March 21, 1907. Serial No. 363,583.

To all whom 'it may concern:

Be it known that I, FOSTER MILLIKEN, a citizen of the United States, anda resident of the city of New York, borough of Manhattan, county andState of New York, have invented a new and Improved Attachment forRolling-Hills, of which the following is a full, clear, and exactdescription.

This invention has reference to improvements in attachments for rollingmills, being especially directed to improvements in theconveyer tabletherefor. v This table may be either fixed or pivotally mounted, thelatter' being ordinarily known as a tilting table, which is used inconnection with rolls more than two high.

In passing structural or other forms of iron to the pass of the rollsfrom the conveyer table, it not infrequently happens that it becomesstuck between the guide-blocks or that the table is elevated at such anangle that the frictional contact of the conveying rollers isinsufficient to carry the metal forward.

The purpose of this invention is to overcome this difficulty byutilizing the power driving the rollers of the conveyer table topositively force the metal into the pass of the rolls or withdraw thesame therefrom. This I preferably accomplish by extending a bearing ofone of the conveyer rollers to the outside of the table and attachthereto a drum of the nigger-head type. A line is passed from this drumto the iron being rolled when the-frictional drive of the rollers failsto move it, the line operating to positively pull or push the iron inthe desired direction as it winds on the drum.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a plan of a rolling mill with one form of my improvementapplied thereto, and Fig. 2 is a side elevation of the saine.

Referring to the drawing, l, l indicates the rolls of the mill throughwhich the metal is passed to bring the same to the desired shape. Thepass between these rolls, which is of various forms,v is fed by aconveyer table 2, which comprises side frames 3 having a train ofrollers made up of rollers 4 journaled therebetween. These rollers areeach provided with a gear 5, which intermesh with adjacent idle gears (iintermediatelyv arranged and acting to positively drive all of therollers n in the same direction when any one of them is rotated.

One of the rollers 4 near the center of the table has the bearingthereof extended beyond the frame 3, to which is attached a drum 7 ofthe nigger-head type. When the frictional contact of the rollers isinsuflicient to deliver the bar of metal, as shown in Fig. l, to thepass of the rolls, which is often caused by the sticking of the barbetween guide-blocks 8 carried by the table, a line 9 is passed from thedrum to either the forward or rearward portion of the bar, which acts towithdraw or force the bar to the rolls according to the point ofapplication of the line, as the same is wound about thedrum 7.

In order that the pull on the bar may be in the direction of itslongitudinal axis for withdrawing it from the rolls, a pulley-block orsheave I is attached in any suitable manner forward of the drum and atthe opposite side of the table, and the line 9 made in the form of aloopwith one strand or member thereof passed over the sheave, the endsof the line being connected up with grappling-tongs ll in a well knownmanner, as indicated in Fig. l. By this construction, as the line 9is'drawn taut the tongs bite into the bar and assist the rollers of thetable in withdrawing it from the rolls as the line is wound about thedrum.

If desired to push the bar to the roll, if it is of suficicient length,the tongs are reversed from the position shown in Fig. I and applied toits outer end at the opposite side of the drum.

The conveyer table, although shown stationarily supported, may bepivotally mounted, in which case it is known as a tilting table and isused in feeding and receiving the metal as it is rolled to and fromrolls more than two high. The invention is especially useful inconnection with this form of table, as in delivering the metal betweenthe top pass of the rolls, the table and metal are at an inclination,necessitating the driving of the metal uphill to carry it to the rollingpass.

The invention is obviously susceptible of numerous modifications fallingwithin the scope of the annexed claims.

Having thus described my invention I claim as new and desire to secureby Letters Patent:

l. A rolling mill, comprising a conveyer table having a train of drivenrollers, one of' which is extended beyond the table, a drum fixed tosaid extended roller, and means for connecting the drum to the materialto be rolled carried by the table.

2. A rolling mill, comprisingl a conveyer table having a train of drivenrollers, a nigger-head fixed to one of said rollers, and a line adaptedto be passed from the niggerhead to the material to be rolled.

3. A rolling mill, comprising rolls having a conveyer table with a trainof driven rollers for frictionally driving the metal to the pass of saidrolls, and a winding drum fixed to one of said rollers, for the purposedescribed.

4. A rolling mill, comprising rolls having a conveyor table with a trainof driven rollers for frictionally drivingl the metal to the pass ofsaid rolls, one of said rollers being extended beyond the table, and anigger-head xed to the extended portion of said roller, for the purposedescribed.

5. A rolling mill, comprising s conveyer table having a train of drivenrollersy :L drum driven from one of said rollers at one side of thetable, u she-ave fixed at the opposite side of the table, und a lineadapted to be passed about said sheave nnd attached to said drum, forthe purpose describe-d.

G. A rolling mill, comprising a eonveyer table having :L train of drivenrollers, one 0f which is extended beyond the table, a nigger-Ahead fixedto the extended portion 0f said roller, n shenve fixed at the oppositeside of the table,

grappling tongs, and a line passing from said nigger-head 1 directly tosaid tongs and from seid nigger-head to said tongs over smid sheave.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
